How similarity works

Source: The RevenueBase company graph: 60 million companies and 398.9 million professional contacts resolved from primary sources, queried with RevenueBase Smart Search, the natural-language company search available to every RevenueBase user.
Matching: Companies are matched on what they actually do, as described in their own business descriptions, never on shared industry codes. The list keeps only matches at 85%+ measured similarity to Horizon Media, and match quality is audited by blind human judging. Read the full methodology.
Ranking: Team size, largest first, among the matched companies: companies are ordered by the number of professionals RevenueBase tracks at each one. Each row also shows its measured similarity to Horizon Media as a percentage.
Verification: Contact records re-verify on a rolling cadence rather than being scraped once and left to decay; each contact's own verification date is shown inside RevenueBase.
Refresh: This page's figures were pulled from the company graph on September 26, 2026. Lists refresh periodically as the graph is re-checked.
